STOOKINGdv'EACI-IINE ELEVATOR.

Application filed September 23, 1921. Serial No. 502,711.

To all whom it may concern:

Be it known that I, NORMAN HOWARD CAUFIELD, a subject of the King of Great Britain, and a resident of the city of Victoria, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Stooking-Machine Elevators, of which the following 18 a specification.

My invention relates to-improvements in stocking machine elevators, and the object of my invention is to provide a device of this nature by means of which the sheaves may be transferred from the binder to the stooker automatically and in a simple, prac tical, and highly efficient manner.

I attain this object by the construction illustrated in the accompanying drawings in which- Fig. 1 is a side view of the elevator.

Fig. 2 is a plan view.

Fig. 3 is a detail view of the elevator shaft arm connection.

Similar figures of reference indicate similar parts throughout the several views.

In the drawings 1 indicates the frame of a stooking machine and 2 the basket, which is represented in the normal horizontal po sition, that is, the sheaf-receiving position, while 3 indicates a portion of the binder elevator platform and 4 the kicker shaft associated with the binding device.

The stooker elevator consists of a frame having two side bars 5 and 6 rigidly connected at one end to the binder platform 3, as at 7, while their opposite ends are formed as bearings 8 and 9 arranged to lie adjacent the side of the stooker frame, as shown, through which bearings extends movably a shaft 10, which shaft is mounted in bearings 11 and 12 secured to the stooker frame, from which it will be seen that the side bars 5 and 6 are firmly supported between the stooker and the binder, and as the widthbetween the bars is less than the length of a sheaf, the bars form a frame or platform on which the sheaves may be deposited, as hereinafter described. Braces 13 and 14 are provided for the side bars, between which braces extends a bar 15, and this bar 15 is preferably supported intermediate its length by a vertical bar 16 extending between the bar 15 and the outer end of a horizontal bar 17 the opposite end of which is formed as a boss 18 through which shaft 10 extends.

Secured to the shaft 10 at spaced intervals and within the frame formed by the 26, and rest normally on the bar 15, and to each of these arms 23, 24 and 25 are secured intermediate their length vertical bars 27 28, and 29 respectively. The position of the bars 27, 28, and 29 with relation to the ends of their respective arms, and the length of the arms themselves, is such that when in normal position, a sheaf deposited on the side bars 5 and 6 will lie directly over the three arms 23, 24, and 25 and between, the bars 27, 28 and 29 and the ends of the arms.

Each arm 23, 24, and 25 being pivotally connected to the arms 19, and 21 is ca pable of swinging movement, but this move ment is limited by means of plates 30, 31, and 32 secured to the ends of the arms 19, 20, and 21 and having their ends turned over, as at 33 and 34, to form stops to limit the swing of the arms, the stops 33 being arranged so that on the upward movement of the elevator under the weight of the sheaf the arms 23, 24 and are straightened out into line with the arms 19, 20 and 21. The spacing of the stops 34, however, is such that when the arms are carried over the top center into position for dumpingthe sheaf, the arms 23, 24 and 25 may fall forward a limited amount, as shown by the dotted lines in Fig. 1.

Loosely mounted on the shaft 10 towards one end is an arm 35 connected by a lever 36 to an arm 37 secured to the kicker shaft 4 the connection being arranged so that while the arm 37 makes a complete revolution the arm 35 only rocks an amount sulficient to raise the elevator arms from the normal position shown by the full lines in Fig. 1 to the position shown by the dotted lines and back again to the normal position. The arm 35 is provided with a notch 38 with. which a squared pin 39 carried by shaft 10 is removably engaged, being held in engage: ment by means of a spring 40 disposed be tween a pin 41 passed through the pin 39 and a plate member 42 secured to the shaft, while it is capable of being withdrawn out of the notch by means of a connection 43 connected at one end to the pin while its opposite end is connected to a crank arm 44 secured to the end of the stooker shaft, indicated generally by the numeral 45, the pin.

39 being prevented from reentering the notch 38 by a' flange 46011 the arm 35' until itiarrives at the correct reentering position.

The manner in which thedevice operates "may be briefly described, it being understood that when the elevator is out of operation the arms lie in the normal position shown by the full lines in Fig. 1. When the binder commences cutting and the first sheaf is kicked on to the arms 5 and (fit remains there until the next revolution of the kicker shaft 45,1but as soon as the kicker shaft commences to revolve to bring the next, or

duringth-e stock depositing operation. The

kicker shaft 4 continues to revolve so that of said shaft having a one or moresheaves may be meanwhile deposited on the arms 5 and '6; and thesearethro'wninto the basket when it returns .to its normal horizontal sheaf-receiving position again since the pin 39 then reenters the notch 38 whereupon the elevator armsresume their operation until the stooker basket is again lled. V I 7 What I claim as my invention is Thecombination with a-stook-ing. ma-- cl ins and a binding machine,- of a framedisposed between said m achines on to which sheaves from the binding machine may be deposited, elevator arms arranged normally below saidframe, ashaft to which said arms are secured, partial rotation of which elevates saidarms toraise the sheaves and dump them into the stocking machine basket, an arm freely mounted on the end flange concentric with the shaft provided with a notch, an armsecured tothe binding machine kicker shaft,

" a connecting rod between said arms,- a pin carried by said elevator arm shaft in slidable engagement with said notch,

I and means for disengaging, the pm out of the notch,

2. The comb nation; with a stocking machine and a binding machine, of a frame disposed between said machines on to which sheaveskf -rom the binding machine'may be deposited, elevator arm-s arranged normally thrown into the basket below said frame, a shaft to which said arms are secured, partial rotation of which elevates said arms to raise the sheaves and dump them into the stocking machine basket, an arm freely mounted on the end of said shaft having a flange concentric with the shaft provided with a notch, an arm secured to the binder machine kicker shaft, a connecting rod between said arms, a pin carried by the elevator arm shaft in sli-dable engagement with said, notch, means for disengaging the pinout of the notch, and means for reengaging the pin in the notch after a predetermined interval of disengagement.

3. The combination with a stooking 1nachine and a binding machine, of a frame disposed between said machines on to which sheaves from the binding machine may be deposited, a shaft mounted adjacent the stocking machine for partial rotation, elevator arm's arranged normally below said frame, each said arm comprising a main portion having one end secured to the said shaft and itsopposite end provided with an extension pivotally connected to it, said extension lying directly under the sheaf re ceiving portion of the frame, a bar carried by each extension disposed at right angles thereto and mechanism operated by the binding machine kicker shaft for operating said elevator arm shaft to elevate through a predetermined travel.

4;.
